French satirical paper Charlie Hebdo attacked in Paris
It comes a day after the publication named the Prophet Muhammad as its “editor-in-chief” for its next issue.
Its cover carried a caricature of the Prophet making a facetious comment.
The editor-in-chief of the magazine, Stephane Charbonnier, said that Islam could not be excluded from freedom of the press.
He said: “If we can poke fun at everything in France, if we can talk about anything in France apart from Islam or the consequences of Islamism, that is annoying.”
Mr Charbonnier, also known as Charb, said he did not see the attack on the magazine as the work of French Muslims, but of what he called “idiot extremists”.
The magazine said Wednesday’s edition was intended to “celebrate” the victory of an Islamist party in last month’s Tunisian elections.
Charb said the magazine had received several threats on Twitter and Facebook before the attack.
“This is the first time we have been physically attacked, but we won’t let it get to us,” he said.
Police said Charlie Hebdo’s headquarters had been petrol-bombed in the early hours of Wednesday morning.
